The Paiutes have a flag that was officially confirmed in 1997. Within it are several symbols for the tribe. First, the colors, white symbolize purity, red and black are both for strength and power, and yellow for healing and life. The biggest symbol is the eagle which represents their deity, then there are a series of images that relate to traditional songs and games the Southern Paiutes would play, the arrowheads that they were known for. Overall, the image is supposed to represent a warrior's shield with the five eagle feathers hanging on the bottom representing the 5 modern-day tribes of the Southern Paiutes.
